Bonn GAUGE.

Application filed July 14,

- of the cityof Canton, county of Stark, and

' of which the following is a specification.

projects beyon State of Ohio, have invented a certain new and useful Improvement in Bore Gauges,

' My invention relates to 'bore gauge and has for its principal object a device that can be attached to a grinding machine or the like in which the bore of a roller bearing cone or similar ring is being ground; so that the bore can be easily and quickly gaged without removing the'work from the grinding machine. Another object is a simple and compact device that takes up little room on the grinding machine and does not interfere'with the grinding tool. t,

The invention consists principally in mounting a pair of gaging members in the chuck of the machine in alinement with'the bore of the article being ground, said gaging members being operatively connected with a rod that extends through the hollow spindle of the machine, whereby theflgaging members maybe operated by moving said rod endwise. The invention further consists in the parts and combination of parts hereinafter described and claimed. 4

In the accompanying drawing Fig. 1 is a longitudinal section of a portion of the grinding machine and showing the bore gauge; and

Fig. 2 18 a fragmentary sectional view of a modified form of gauge.

In the drawing the invention is shown in connection with a machine for grinding the bore of a roller bearing cone. The roller bearing cone 1 is held in a suitable chuck 2 that; is mounted on a hollow rotary spindle 3 on the grinding machine, such constructionforming no part of the present invention and being shown only diagrammatically. The grinding tool for grinding the bore of the cone is indicated at d, but is not shown in detail. I

Mounted in the hollow spindle 3 is a sleeve 5 that is loosel mounted on a rod 6 that d the spindle at both ends. ivotall ;secured to the rod 6 is an operating han' e 7 that is secured to a projecting member. 8 on the frame of the machine,

whereby the r iid 6 may be moved lengthwise of the spindle 3. The handle may have an 1923. Serial No. 651,839.

opening through which the rod extends and may be secured to the rod by collars 9 on said rod. 1

The sleeve has an enlarged end portion 10 against which one of the collars 9 abuts after the rod has been moved a certain distance 1 toward the cone 1 and thereafter the rod carries the sleeve. with it,

Mounted on the end of the rod 6 is a the sleeve 5 is of reater size than the boreof a normal cone, t a tis it is a no go ring,

After the bore of thetcone has been ground the tool is removed f om the bore and the rod 6 is moved to the right (toward the cone), if the bore is of the exact size desired the gaging ring 11 just enters the bore of the cone. The continuedmovement of the rod 6 moves the sleeve 5 withits gaging r ng 12 towards the .cone. If this gaging ring enters the bore it shows the operator that the hole is too large, but if it does not enter the bore it shows that the work is satisfied tor T n Fig. 2 is shown a slightly modified construction in which both gaging rings are mounted on a single rod 6*. In the form shown in 2, the end of the rod 6*- is bored out and a portion thereof threaded,

and a threaded pm 21 is mounted therein,

The projecting end of said threaded pin is threaded and a gaging ring 22 is mounted thereon and a gaging ring'23 is also mounted oh the end of the rod.

The'ga ing ring 22 nearest t a work may be of smaller diameter than that of a normal bore and the other gaging ring 23 may be of the exact size of a normal bore. in such case, the bore is ground out untilthe first gaging ring 22 easily enters it; and then the rindin'g is red with slowly, and the %ore w! rom time to time until the second ring 8; able to enter it..

The herein desc'ri bore gauge has numerous advantages. It is s mple and com grindin gauge t e bore ofthe work without remov- 'ing the work from the machine and without having to move the cutting tool far from the work. The gaging rings are easily removed.- Thus the device is. enabled to be easilychanged to gauge rings of diflercnt sized bores and worn gaging rings may be easily replaced. Obviously, numerous changes may be made Without de arting from the invention and I do not wis to be limited to the precise construction shown.

What I claim is:

1. In combination with a machine for enlarging the bore of annular..-articles comprising a rotary chuck and hollow spindle, a gauge disposed in the chuck for gaging the ore of the annular article, and means extending through the bore of said spindle for supporting said gauge.'

2. In a grinding machine or the like for grinding the bore of annular articles comprising a rotary chuck and hollow spindle, a

7 pair of gaging members disposed Within the chuck in axial alinement with the bore of the annular article, means for supporting 7 said gaging members and means for moving first one and then the other of said gaging members into the bore of the annular article. 3. In a grinding machine or the like for grinding the bore of annular articles comprising a rotary chuck and hollow spindle, a pair oi gaging members disposed within the chuck in axial alinment with the bore of the annular article, one of said gaging members being smaller than the other, means for moving first the smaller and then the larger of said gaging members into the bore of the annular article and means for suping members being in axial alinement with the bore of the cone, said rod having a handle for moving it endwise, and a collar porting said gaging member.

4, In a grinding machine or the like for grinding the bore of annular articles, comprising a rotary chuck and hollow spindle,

a rod extending through said spindle and into said chuck, agaging member mounted on the end of said rod in axial alinement lid with the bore of an article being ground, a second ing member disposed in axial alinementwith said bore, means operatively connecting said second gaging member with St/Lid rod and means for moving said rod endwise, thereby moving first one and then images the other a'rod extending through said spindle and into said chuck, a gaging member mounted on the end of said rod in axial alinement -'vvith the bore of an article being ground, a

second gaging member disposed in axial alinement with said bore, means operatively connecting said second gaging member with said rod, one of said gaging members being of larger diameter than said other, and means for moving said rod endwise, thereby moving first one and then the other gaging member into the bore of the article.

6. In a grinding machine or the like for grinding the bore of roller bearing cones and the like comprising a rotary chuck and hollow spindle, a rod extending through said spindle and into said chuck, a sleeve slidably mounted on said rod, a circular gaging member mounted on the end of said rod, a second circular gaging member mounted on the end of said sleeve, said gaging members being in axial alinement with the bore of the cone, and means for moving said rod and said sleeve endwise to-bring first one and then the other gaging member into the bore of said cone 7. In a grinding machine or the like for grinding the bore of roller bearing cones and the like comprising a rotary chuck and hollow spindle, a rod extending through said s indle and into said chuck, a sleeve:

on said rod adapted to abut against the end of said sleeve after the rod has moved'far gaging member into the bore of l the' article.

'5. In a grinding machine or the like for enough that the gaging member on the end thereof has passed through the bore of the cone, thereby moving the gaging member on @SWALD 'SCI-ILAUIPIIZ.
